Abstract
A projection formula coriolis plate comprises a transparent organic glass plate that is arranged in the groove of the three groove-provided pulleys positioning in a same plane, wherein one pulley is an active pulley and the other two are positive pulleys. The transparent organic glass plate is provided with a spring gun, the cavity of the spring gun is provided with a launching round steel ball. The spring gun can fix on different positions of the transparent organic glass plate through the sucker. The product realizes the level maintenance of the coriolis plate in rotating and realizes projection and transparency and eliminates the rotary axis usually arranged in the middle. When operating, plurality times of experiments can be carried on by moving the position of the spring gun and different states of coriolis. The utility model has the advantages of simple structure, easy operation, and good demonstration visual impression.
Description
Technical field: the utility model relates to a kind of projection Coriolis force dish, belongs to instruments used for education.
Background technology: Coriolis force is a difficult point of theoretical mechanics, and it is more abstract, up to the present, does not also have very good instrument that it is shown.The apparatus for demonstrating of the Coriolis force of prior art is provided with central shaft in the middle of it, and is opaque, can not demonstrate out its experimental result intuitively.
Summary of the invention: the purpose of this utility model is to remedy the deficiencies in the prior art, and provides a kind of phenomenon that can movement locus of object be departed from Coriolis force to project to projection Coriolis force dish on the screen.For achieving the above object, the utility model adopts following technical proposals: projection Coriolis force dish, comprise transparent organic glass dish (4), transparent organic glass dish (4) is positioned in the groove of the pulley (1) that is in conplane three troughs of belt, (5), (6), its middle pulley (5) is a driving pulley, and pulley (1), (6) are by travelling block.Transparent organic glass dish (4) is provided with spring gun (3), establishes emission round steel ball (2) in the cavity of spring gun (3).
Characteristics of the present utility model are that it has realized Coriolis force dish maintenance level in rotation, realize that projection is with transparent and remove the rotation axis that places the centre usually.During operation, can repeatedly test, can get the Coriolis force of different conditions by the position of mobile spring rifle.Have simple in structure, processing ease, characteristics that demonstrating visual's property is good.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
With reference to Fig. 1, projection Coriolis force dish comprises transparent organic glass dish 4, and transparent organic glass dish 4 is positioned in the groove of the pulley 1,5,6 that is in conplane three troughs of belt, and its middle pulley 5 is a driving pulley, and pulley 1,6 is by travelling block.Transparent organic glass dish 4 is provided with spring gun 3, establishes emission round steel ball 2 in the cavity of spring gun 3.Described spring gun 3 can be fixed on the diverse location of transparent organic glass dish 4 by sucker.Pulley 5 links to each other with motor, and when motor rotated, pulley 5 drove pulley 1,6 and then drives organic glass dish 4 again and rotates.
Using method:
1, the Coriolis force dish is placed the top of projector, open projector;
2, start motor, the spring gun on transparent organic glass disc spins and then the drive dish rotates on surface level together;
3, vertical infrared transmitter ejects the steel ball in the spring gun, and at this moment the movement locus of steel ball is projected on the screen;
4, the position of mobile spring rifle, the experiment of reforming can get the Coriolis force of different conditions.
Claims (2)
1, a kind of projection Coriolis force dish, comprise transparent organic glass dish (4), it is characterized in that: transparent organic glass dish (4) is positioned in the groove of the pulley (1) that is in conplane three troughs of belt, (5), (6), its middle pulley (5) is a driving pulley, pulley (1), (6) are by travelling block, transparent organic glass dish (4) is provided with spring gun (3), establishes emission round steel ball (2) in the cavity of spring gun (3).
2, projection Coriolis force dish according to claim 1 is characterized in that: described spring gun (3) can be fixed on diverse location on the transparent organic glass dish (4) by sucker.
